RAZOR-STROPPING MACHINE.

SPECIFICATION forming m. of Letters retentiv 686,549, dated November 12,1901.

Application filed July 3, 1901.

Serial No. 67,012. (No model) To (all who/10 it mu-yco/wcr/t:

Be it known that I, ALBERT L. SILBERSTEIN, a citizen of the UnitedStates, and a resident ing blades of different sizes and which isarranged to allow of conveniently placing the razor in position in theholder and securely holding it in place therein, the machine when in usegiving the blade the desired inclined position while drawing it over thestrop in either direction, so as to present the entire cutting edge ofthe blade to the strep at. each forward and backward movement.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out intlle claims.

A practical embodiment of the invention is represented in theaccompanying drawings, in which similar characters of reference indicate corrosponding parts in all the views.

Figure l. is a front elevation of theimprovement with the parts in anormal centralposition. Fig. 2 is a like View of the same with the partsin active position and the razor in place in the blade-holder. Fig. 3 isan en larged trr-insversc section of the improvement. Fig. i is an endview of the same. Fig. 5 is an enlarged cross-section of theblade-holder thin razor-blade in position therein, and Fig. 0 is a like'view of the same with a thick razor-blade in position in the holder.

On the forward end A ot'a handle A is arranged a pivot 13, on which istulcrumed the heel U of a cross-bar forming part of the frame 0, havingparallel arms C, adapted to rest upon the strop when ,the machine isused for strop'ping the razor, as hereinafter more fully described.

The blade-holder D for curelyholding the blade E receiving, and se--.vided at its inner end with a spindle I), jour-p ;naled in suitablebearings arranged in the cross-bar C of the frame b, and on saidbladeholder is secured a pinion F, in mesh wit-h a segmental rackli",formed or secured on the outer portion or the end A of the handle A.

The frame 0 and the blade-holder l) are normally held in a centralposition, as shown in Fig. 1, by the use of a spring or springs G,coiled on the spindle D" and connected at one end with the spindle andat the other end with the cross-bar C of the frame t, so that whensaidframe is swung into an angular position, either to the right or to theltf', as indicated in full and dotted lines in Fig. 3,- then the springor springs G are put under tension, and as soon as the frame C releasedLl'ie pressure of the spring or springs will cause the spindle D torotate,'so as to cause the pinion F'to roll off on the segmentalgear-rack F to bring the frame 0 and tinholder D back to the centralposition shown 'in Fig. 1. Vthen the holder D .is in this cen- 'tralposition, its longitudinal opening stands forward to allow ofconvenient-1y inserting the blade E intotheblade-holder and at the sametime'hold the cutting'edge of the blade away from the strop engaged.byt-he supportingarms C of the frame C.

Misunderstood that in contact with the draws the handle frame C swingsinto the inclined position shown in Fig. 2 to cause the edge of theblade E to move in contact with the strop, so that whenthe armsC arestrep and the operator A from right to'lelt then the during the movementfrom the right to the left the blade is honed at one side. On thereturnstroke-that isythe movement from the left to the right- -the frameswings tirst into the angular position shown in dotted lines in Fig. 2,and during this movement the pinion F is forced to roll olf on thesegmental rack F to turn the blade-holder D over, so as to bring theother side of the cutting edge of the blade E into contact with thestrop. As soon as the arms 0'' are lifted off from the strop the springUr immediately causes the frame Gand the'blade-holder l) to swing backtoanormal central posit-ion, as shown in Fig. i, so that the cuttingedge of the blade exof the razor is protends to the front away from thestrep,

In order to limit the swinging movement of the frame C on the pivot l3,I provide the handle end A with beveled shoulders A, adapted to beengaged alternately by the flat back of the heel C, as will be readilyunderstood by reference to Fig. 2. In order to hold the handle E of therazor E in p'roper position during thestropping ofthe blade, I provide.an extension handle-support II, mountedto slide lengthwise on theblade-holder D, the outer end of the handle-support having prongs II forreceiving and clampingthe handle E when the latter is extended, as shownin Fig.

2. The inner end II of the handle-support 4 provide the holder D at theinside with a longitndinally-extcnding spring I, seen red at the outerend to the bottom of the holder and having its free end resting looselyon the said bottom near the inner end of the holder, as is plainlyindicated in Fig. 3. Now by slid:

ing the razor-blade into position in the holder its baekis moved intocontact with the spring I, and the latter consequently forces the bladeoutward, .so as to pressits sides into firm contact with the sides ofthe holder to securely hold the blade in position in the holder, as willbe readily understood by reference to Figs. 5 and 6.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A razor-stropping machine, comprisinga handle,having a lixed segmental rack and inclinedv shoulders, a frame pivotedon the said handle and having a pair of arms adapted to rest on thestrop, the said frame having the flat back of its heel arranged to abutalternately on the said shoulders when the machine is in use, ablade-holder journaled on the frame between the said arms, and a pinionon the spindle of the said blade-holder and in mesh with the saidsegmental rack, as set forth. a

2. A razor-stropping machine, comprising a handle having a fixedsegmental rack and inclined shoulders, a frame pivoted on the saidhandle and having a pair of arms adapted to rest on the strop, the saidframe having the flat back of its heel arranged to abut alternately onthe said shoulders when the machine is in use, a blade-holder journaledon the frame between the said arms, a pinion on the spindle of the saidblade-holder and in mesh with the said segmental rack, and a springpressing the spindle of the blade-holder for returning the frame andblade-holder to a normal central position, the heel-back then being outof engagement with the said shoulders, as set forth. I

3. A razor stropping machine having a blade-holder provided with meanssecured to the holder and extending at the inside thereof for engagingthe back of the blade inserted into the holder for pressing the bladeoutwardly and forcing the sides of the blade in firm eontact with thesides of the holder, as set forth.

t. A razor-stropping machine having a blade-holder and a springextending lengthwise of the blade-holder along the bottom thereof forengaging and pressing against the back of the blade inserted into theholder, one end of the spring being secured to the blade-holder at theentrance end thereof, as

set forth.

5. A razor-stropping machine having a blade-holder for receiving theblade of the razor and a handle-support mounted to slide on the saidblade-holder so as to form an extension thereof, as set forth.

6. A razor-stropping machine having a blade-holder for receiving theblade of the razor, a handle-support mounted to slide on the saidblade-holder to form an extension thereof, and means forlimiting theoutward sliding motion of the said handle-support onthe saidblade-holder, as set forth.

In testimony whereof I have signed'my name to this specification in thepresence of two subscribing witnesses.

ALBERT L. SILBERSTEIN.
